CASEMEN'T WINDOW Filed oct. 2s. 1951 INVENTOR ATTORN EYS Patented Nov. 8i, 17932 DONALD a LoBELL, or BALTIMQRE; MARYLANDH i CASEMENT wiiviiow Application led October 23, ISA-331..- SeriaI No. 5715,.7'0-17,v I

This invention relates tok easement windows of metallic construction and has for the primary object, the provision of a device of the above stated character which is so constructed as to pre-vent the entrance of air and weather elements when in a closed position by establishing inner and outer seals between the window frame and the sash.

Another object of this invention is the 0 provision of a window frame and sashframe both constructed of channeled material so that when brought into engagement an iiiner seal against weather elements is provided and means being provided on the window frame to establish an outer seal and capable of yielding under pressure to permit the window sash to assume a fully closed position without binding or undue strain thereon.

With these and other objects in view, thisV invention consists in certain novel features of construction, combination and arrangement of parts to be hereinafter more fully described and claimed.

For a complete understanding of my in-l vention, reference is to be had to the following description and accompanying drawing,V

in which Figure l is a fragmentary perspective Vview illustrating the easement windo-w constructed in accordance` with my invention.

Figure 2 is a sectional view illustrating the same.

Figure 3 is a fragmentary sectional view illustrating the vmeans of forming the innerseal. e

Figure 4 isa fragmentary perspective view illustrating a weather strip carried by the window frame' and engageable with the window sash when in a closed position to form an outer seal. l

Referring in detail to the drawing, the

numeral 1 indicates a window frame ofv the Casement type having associated therewith a window sash 2 adapted to swing relative to the frame on hinges 3 Vfor the purpose of opening and closingthe window.`

The frame 1 is of channel iron construction providing inner and outer walls 4 and 5 and by referring to Figure 1 it will be noted that the inner wall 4 n 9i A' 'seal/ing element Vreferring to Figure 1 projects beyond lthe free edge of the-outer wall 5 to -formga seat, 6"for the window sash 2 "tofengage when in a closed position and thereby:establishfan inner lseal against weatherlelements. Y' I Thewindow sash 2"-is constructedwfroin angle yiroi'i providingy walls 7 Vand 8.V The hingesfS are suitably connected to the wa'llsiy 5 and 7 and the wall 8 of the window sash is bent angularly tojform anattacliing flange 10 is. mounted;` on the' 60 Hangs' 9"'and projects beyond the opposite'- faces of the-wall 8 so as to contact withy one 1 o-f the faces of the wall 4 or the seat Gwhen the A'window sash is in aclosed position. The' sealingv element 10 is bent upon itself to re- '65M cei've' the flange`9 with the free edges in abutting engagement with the wall 8 thereby firm'- ly securing or sealing the element 10 in position V on-the Vwindow sash. A'Ihe portion of. thesealiing element 10 Voverlying the outer T0 facerrof the flange 9 forms an abutment'llV for-the glass 12 to'engage and theV glass'lQ is held in engagement therewith as shown at 13.- A sealing element 14 is 4arranged on the window'frame and iskengage'dby thefwall 7 of the window sashV when said, sash is ina closed position thereby establishing an outer seal against weather elements.- The element 14 is constructed. from a resilient yieldable metal and includes formed upon oneedgea retaining flange 16` and theopposite edgeiis formedwith' a yield.`

a-ble portion 17. The element -14'when"ap' pliedl to theJ frame lprovides'the outer seal. byhaving the yieldable portion 17 disposed y over the wall 5 of the frame so that whenvv the window'sash. is -moved into a closed posi-l tion,v the wall 7 thereof bears against the yieldable portion v17 and slightly `fieXes the same,v thereby preventing the.` entrance of weather elements between the walls 5 and 7. The .portion15 of the element'14 lies against the inner face of the wall 5 ofthe-frame 1 and is held thereagainst by a filler or attaching element `18 of substantially Ufshapev in cross section and is secured within the" frame 1 by bolts or likefasteners 19. By

it willbe seenl that the filler or attaching element 18 bears against the flange 16. of the element 14 thus firmly 100 av .portion `15 -having'o y anchoring the sealing element 14 against displacement and which will permit the portion 17 thereof to overlie the outer face of the Wall 5 and to yield under pressure brought about by the Wall 7 of the Window sash engaging the same. In the construction of'Window easements of this character itis necessary that the Wall 7 of the Window sash be spaced a short distance from the Wall 5 of the frame 1 When the Window sash is'in a closed position and to prevent Weather ele-v ments from entering this space the sealing element 14 is provided, thus it Will loe-seen that the easement is provided With inner and outer seals When the Window lsash is in a' closed position thereby providing a positive prevention of the entranceof Weather elements When theWindoW sash is closed.

It is to be understood that in the manufacture of this devicethe sealing elements 10 and 14: are constructed of sections to conform to the top, bottom and sides'of the frame.. l 1 l wWhile I have shown. and described the preferred embodiment of my invention, it Will be understood that minor changes in construction, combination and arrangement' of parts may the 'spirit and scope of my invention, as

Having thus described my invention, vvhat I claim is:

A'casement Windowv comprisingl a frame of channeled construction providing inner and outer Walls, a lsash hinged to the vframe and of anode iron construction rovidin a air of Walls arranged at right angles to each other, one of said Walls bent angularly to form a, flange, a sealing element carriedbyl the flange and projecting beyond opposite faces of the respective Wall of saidflange to engage the inner Wall of the frame when the.

sash is in a closed position to provide an inner'seal, a strip mounted in the frame and having an angularly disposed yieldable portion disposed over the outer Wall of the frame to be engaged by the other Wall of the sash When the latter is in a closed position topro.- vide an outer seal,'said strip bent to engage `inner faces of angularly related .Walls ofthe frame and an attaching -medium removablysecured in the frame and of substantially Uf shape in cross section engaging and forcing the strip against the inner faces of the angularly related Walls of the frame.

In testimony whereof I affix vmy signature.
